java adding to path
Adding something to the path just makes the commands in the folder available everywhere system wide. The way an OS (not limited to Windows) works is that it searches certain folders for the commands you enter in the terminal (console). If it doesn't find the command, it tells you that the command you entered is not recognized. By adding a folder to the path you tell the OS to also search that particular folder when you enter a command. For Java, you need javac and java from the console. The former compiles your source code, the latter executes it. Had you not added the folder to the path, you would always need to type C:\Program Files\Java\jdk-17\bin\javac when you want to compile a program. By adding the folder to the path javac becomes sufficient. More on reddit.com

August 5, 2023What are we actually doing when setting Environment path variable?
When you write a command on the shell, the system searches the PATH for that command, and then executes it. For example, suppose you are using Windows, the prompt looks like this: C:\> Suppose you type this command: tickle me elmo That command says to look for a program called "tickle" (on Windows this program would be called something like tickle.exe or tickle.bat) and to pass that program the two arguments "me" and "elmo". Since "tickle" is not a built-in shell command (like "cd"), how the system looks for that command is by searching the PATH. Every directory on the PATH is searched in order. If a program called "tickle" (or tickle.exe, etc. on Windows) is found in the first path on PATH, then that program is called. If there is no "tickle" command on the first path in PATH, then the second path in PATH searched, and so on. If no program called "tickle" is found anywhere on the PATH, then you get some sort of error message. On Windows it looks something like this: 'tickle' is not recognized as an internal or external command ... So the analogy of the word 'PATH' is that you are walking down a path, perhaps in a market. You walk down the path and look at various things in the market, and eventually settle on one thing or another. At least that's the idea that I get from the word PATH being chosen for this concept. This idea works pretty similarly on Windows, Linux, and macOS. The details and error messages are slightly different though. For example on Windows, the current directory (C:\ in the above example) is always searched, even if it is not on the PATH. On Windows, there are certain file extensions that are searched as well (e.g. tickle.exe, tickle.bat, tickle.cmd). On Windows, PATH entries are separated by ; instead of :, and on Linux and macOS PATH entries are separated by : instead of ;. Also, on Windows, PATH is also used for looking up dynamic library files (also called DLLs). On Linux, the environment variable LD_LIBRARY_PATH is used instead for dynamic library files. I'm not sure what macOS uses for library files. So how does this relate to Java? For Java the most likely commands you are going to use are 'java' and 'javac'. When you set your PATH to use Java, you are probably making it easy for you to call those programs. 'java' is the command for the Java JVM, and 'javac' is the command for the Java compiler.

In short, it provides a list of directories where executable files can be found without specifying the full-path to the binary.
If you open a command-line-interface on your machine, you can type many commands without having to specify the path to the program. i.e. fdisk, shutdown, ipconfig, nslookup, etc... Keep in mind, that there are also some built-in commands that are built into the command-line-interpreter that are not a separate program... like dir, echo, cls, etc...
The purpose the JRE/JDK wants to modify your PATH environment variable is simply to be able to type java at the command-line without having to specify the full path (i.e. "c:\Program Files (x86)\Java\jre1.8.0_211\bin\java.exe")
You can modify/view your own PATH environment variable by clicking on the search-bar in windows, and type in "edit the system environment variables".
There are actually 2 sets of environment variables, and they will get merged when you open the command prompt. The ones listed under "System variables" affect the whole system, and all users that log into that computer. The ones listed under "User variables for blahblah" only affect the currently logged in user.

Basically, the PATH it defines a set of directories on which programs will be searched for when only the program name is provided, instead of an absolute/relative path.
This is how the OS can find the right program to run when you only type "java" in the terminal, for instance.
Otherwise you would have to provide the full path, like "%JAVA_HOME%/bin/java".

Maybe in some not so simple words, since this is overall an interesting and useful topic. Environment variables are a set of variables accessible to each program alongside the more common command line arguments. On Unix systems these variables are lines of text, each line a different variable in the form of: =. These lines are passed from parent to child process. This means that if you change or add a variable in one shell, this change is visible to that shell and any program you run from there, but isn't visible to programs run else where. I'm not sure how this is solved on windows, but I would expect something similar (except that Windows doesn't have the same process hierarchy). Some of these variables have special meanings, and can change the behaviour of programs. The variable PATH for instance, tells bash (and other programs as well) where to look for commands. So when you type the command "java", it first checks if this is a built-in commands. Since it's not it searchers every directory in the PATH variable, to see if it can find the program "java" there. On Linux these are widely used as an alternative way of configuring the behaviour of commands/programs. One of their benefits is, because of their propagation, it's easy to set up separately configured environments in different shells.

For example, to add a directory to the PATH environment variable, add the following line at the end of "~/.bashrc" (or "~/.bash_profile", or "~/.profile"), where ~ denotes the home directory of the current user, or "/etc/profile" for ALL users. // Append a directory in front of the existing PATH export PATH=/usr/local/mysql/bin:$PATH · (For Java) You can set the CLASSPATH environment variables by adding the following line.
